Nyob rau hauv cov txheej txheem ntawm cov tsev loj thiab txuas hniav, cov qauv EuropeanHEA1000 S355J2 H beamplays lub luag haujlwm txhawb nqa tseem ceeb. Nws lub zog siab thiab zoo heev bending thiab shear kev ua tau zoo tso cai rau nws los tiv thaiv kev loj heev ntsug thiab kab rov tav loads.
HEA1000 S355J2 H-beam yog dav siv nyob rau hauv loj ua lag luam complex, siab- nce vaj tse, txuas hniav, thiab cov chaw ua lag luam uas yuav tsum tau hnyav load- bearing muaj peev xwm, ua rau nws ib tug tseem ceeb feem ntawm niaj hnub steel qauv.
Specification ntawm HEA1000 S355J2 H beam
Lub "990" yog hais txog tag nrho seem qhov siab ntawm 990 hli, thaum lub "300" qhia lub flange dav (piv txwv li, "tis" ntawm ob sab) ntawm 300 hli. Ob qhov ntev no ua ke txhais tag nrho cov macro profile ntawm tus tswv cuab. Qhov "16.5" thiab "31" qhia txog qhov tuab ntawm lub vev xaib (qhov nruab nrab ntawm qhov txuas ntawm flanges) thiab flange, feem.
Thaum bearing ntsug loads, lub web feem ntau resists shear rog, thaum lub flanges, nyob deb ntawm lub nruab nrab axis, mas tiv thaiv tensile thiab compressive stresses generated los ntawm dabtsi yog khoov.
Ib lub web uas nyias nyias (16.5 hli) ua kom muaj peev xwm shear txaus thaum txo tus kheej - qhov hnyav ntawm cov qauv. Lub thicker flange (31 hli) tso ntau cov khoom ntawm ntug cheeb tsam uas muaj kev ntxhov siab ntau tshaj plaws, ua kom cov seem tsis kam rau khoov deformation, piv txwv li, nws ntu ntu ntawm inertia.
Qhov "thick{0}}flange, nyias-web" configuration yog qhov laj thawj tseem ceeb uas yog vim li cas HEA1000 S355J2 H beam tuaj yeem ua tau zoo heev bending nruj nrog tus kheej qis - hnyav.
